I've always been scared of advertising folk. I've met them at parties and I've been to their offices and I've always found them intimidatingly cool. At one company I visited they held their meetings in a caravan that had somehow been installed in the place a rather more exotic place to gather than the typical BBC glass box.
I think there's something quite interesting about the almost tragic quality of a lot of overwrought prose because it has a much more self-conscious awareness of its own failure to touch the real.
